Communism Dies in Russia
The USSR ultimately fell because Containment Policies had worked. Communism had fallen and the US and USSR now could back off of each other.
The photo above shows the tenth year anniversary of the USSR breaking up. Now, all of the countries are separate governments and countries.
Some of the countries have formed back together since the USSR broke up. Germany is now one country again. Unfortunately, there is still a North and South Korea. North Korea is still communist. South Korea is not.
